Telehealth Usage in Otolaryngology: A Comparative Study Pre‐ and Post‐COVID‐19

Abstract The COVID‐19 pandemic led to increased telehealth utilization in outpatient otolaryngology settings. While other studies on telehealth usage in otolaryngology settings have focused on demographic disparities during the pandemic, none have yet assessed how these demographic disparities have evolved from before versus after the pandemic. This study examines 4 recent consecutive years of demographic and clinical data from a large hospital system to investigate how the COVID‐19 pandemic has changed demographic patterns in telehealth utilization. We demonstrate substantial increases in the number of otolaryngology patients participating in telehealth since the beginning of the COVID‐19 pandemic but with no differences in patient distributions by race or ethnicity over time. We also found that telehealth patients, on average, were younger, more likely to be English‐speaking, and more likely to be female. While these disparities widened slightly after the start of the pandemic, they were also present prior to the pandemic.

T he early COVID-19 pandemic led to surgical delays and increased telehealth usage in outpatient otolaryngology settings. 1,24][5][6] Since the pandemic, telehealth infrastructure has expanded substantially. 3 Despite the growing popularity and utility of telehealth, there are concerns that increased telehealth usage may exacerbate health disparities.
][8][9][10] One study of an academic tertiary care practice found that older, male, and lower-income patients were less likely to complete an otolaryngology telehealth visit, but did not find differences by race/ethnicity. 6A larger and broader study found that older, non-English speaking, and Asian patients had lower telemedicine utilization. 7While these studies characterized disparities in telehealth usage during the pandemic, none have described how demographic differences in otolaryngology telehealth usage have evolved since before the pandemic.Our aim is to investigate how the pandemic contributed to demographic changes in otolaryngology telehealth by examining 4 recent consecutive years of data (2019-2022).

Methods
We obtained nonidentified clinical data using the STAnford Research Repository (STARR), which collects patient demographic and clinical information from patients treated at Stanford-affiliated clinics.This study was approved by the Stanford Institutional Review Board (IRB #64700).Adult otolaryngology patients seen via telehealth at 3 Stanford-affiliated clinics were included in this study, between January 1, 2019 and December 31, 2022.These clinics included the main university hospital, one comprehensive otolaryngology clinic, and one otology/neurotology clinic.Telehealth visits were defined as either telephone calls or virtual outpatient visits.We obtained patient demographic characteristics including age, race/ethnicity, gender, and primary language.We utilized t-tests and chi-square analyses to compare demographic characteristics of telehealth patients in 2019 versus 2020 to 2022.For all analyses, a P < .05 was considered significant.All analyses were completed using Stata 14 (Stata Corp.).

Results
The average age of otolaryngology telehealth patients decreased between 2019 and 2020 to 2022 (57.52 years in 2019 vs 55.32 years in 2020-2022, P < .0001;Table 1).Additionally, the number of telehealth patients increased from 3102 in 2019 to an average of 4616 telehealth patients annually from 2020 to 2022 (Figure 1).The percentage of white, non-Hispanic patients as a proportion of total patients decreased from 53.38% in 2019 to 51.55% in 2020 to 2022, driven primarily by an increase in the proportion of patients classified as other or unknown from 24.76% to 27.03% (P = .112).The percentage of female patients as a proportion of total patients increased by 3.17% from 53.24% in 2019 to 56.41% in 2020 to 2022 (P = .006),while the proportion of English-speaking patients increased by 2.02% from 89.72% in 2019 to 91.74% in 2020 to 2022.
When looking at annual trends in percentage of Englishspeaking patients, the largest 1-year change was between 2019 and 2020 (2.06 percentage points), with smaller annual changes occurring between 2020 and 2022.The proportion of English-speaking patients decreased in 2022 relative to 2020 and 2021, with overlapping 95% confidence intervals when comparing 2022 to 2019 (Figure 2A).Gender showed a steadier and more persistent annual change from 2019 to 2022, with an average increase of 1.50% in proportion of female patients each year (Figure 2B).

Discussion
Our study demonstrates substantial increases in the number of otolaryngology patients participating in telehealth postpandemic.Additionally, we demonstrate that postpandemic, telehealth patients were younger and more likely to be English-speaking and female.These disparities were present prepandemic and either widened or persisted through the pandemic.Low rates of telehealth adoption among non-English speakers have also been documented in other studies, with potential explanations including challenges with real-time translation and with navigating telehealth software. 9,11e found that the proportion of female otolaryngology telehealth patients increased annually, widening the gender gap that was documented prepandemic. 7,9,12One potential explanation is higher levels of eHealth literacy among women, 13 which could have led to quicker uptake of
